ABSTRACT:
A pneumatic transfer apparatus (10) includes a service provider terminal (22) and a customer terminal (24). A carrier (32) is moved through a transfer conduit (26) between the customer and service provider terminals by a differential pressure generating mechanism (28, 30). Each of the customer and service provider terminals includes an actuator mechanism (54, 82). The actuator mechanism is operative to orient an opening in the housing of the carrier with a transfer opening in the transfer conduit. The actuator mechanism is further operative to move an inner shell (100) relative to an outer shell (96) of the carrier so as to bring openings in said inner and outer shells into alignment which enables accessing the interior area of the carrier.
